Abstract (en)
A multiprocessor system includes a judging unit (24) judging whether a read command inputted to a global address crossbar (200) is a read command to a memory (11) on an own system board (100), an executing unit (23) speculatively executing, when the judging unit (24) judges that the read command is a read command to the memory (11) on the own system board (100), the read command before global access based on an address notified from the global address crossbar (200), a setting unit (26) setting for queuing data read from the memory (11) in a data queue (27) provided on a CPU without queuing the data in a data queue (41) provided on the memory (11), and an instructing unit instructing, based on notification from the global address crossbar (200), the data queue (27) provided on the CPU to discard the data or transmit the data to the CPU.
